| 1 | +# BUILD_PR_LEVEL_19_2_RUNTIME_LIFECYCLE_VALIDATION Report |
| 2 | + |
| 3 | +Date: 2026-04-16 |
| 4 | +Scope: runtime lifecycle validation only (no implementation changes) |
| 5 | + |
| 6 | +## Objective Coverage |
| 7 | +- Boot sequence |
| 8 | +- Runtime loop stability |
| 9 | +- Shutdown behavior |
| 10 | +- Reset/reload flows |
| 11 | +- Error-handling paths |
| 12 | +- Full-suite status |
| 13 | + |
| 14 | +## Commands Executed |
| 15 | +1. `node --input-type=module -e "import('./tests/core/EngineSceneLifecycle.test.mjs').then(m => m.run())"` |
| 16 | +2. `node --input-type=module -e "import('./tests/core/EngineTiming.test.mjs').then(m => m.run())"` |
| 17 | +3. `node --input-type=module -e "import('./tests/tools/RuntimeSceneLoaderHotReload.test.mjs').then(m => m.run())"` |
| 18 | +4. `node --input-type=module -e "import('./tests/tools/HotReloadSystem.test.mjs').then(m => m.run())"` |
| 19 | +5. `node --input-type=module -e "import('./tests/tools/AssetErrorHandlingStandard.test.mjs').then(m => m.run())"` |
| 20 | +6. `npm test` |
| 21 | +7. `node ./scripts/run-node-tests.mjs` |
| 22 | +8. `node --input-type=module -e "import('./tests/runtime/LaunchSmokeAllEntries.test.mjs').then(m => m.run())"` |
| 23 | + |
| 24 | +## Validation Results |
| 25 | + |
| 26 | +### Boot -> Run -> Shutdown |
| 27 | +- `PASS EngineSceneLifecycle` |
| 28 | +- `PASS EngineTiming` |
| 29 | +- `PASS LaunchSmokeAllEntries` with `PASS=271 FAIL=0 TOTAL=271` |
| 30 | + |
| 31 | +Interpretation: |
| 32 | +- clean startup confirmed in unit lifecycle and end-to-end launch smoke |
| 33 | +- stable frame/tick loop behavior confirmed |
| 34 | +- clean shutdown confirmed by lifecycle tests and no launch-smoke residual failures |
| 35 | + |
| 36 | +### Reset/Reload Flows |
| 37 | +- `PASS RuntimeSceneLoaderHotReload` |
| 38 | +- `PASS HotReloadSystem` |
| 39 | + |
| 40 | +Interpretation: |
| 41 | +- targeted reload path works |
| 42 | +- invalid reload keeps last known good runtime |
| 43 | +- runtime disposal path executes cleanly |
| 44 | + |
| 45 | +### Error Handling Paths |
| 46 | +- `PASS AssetErrorHandlingStandard` |
| 47 | + |
| 48 | +Interpretation: |
| 49 | +- standardized asset error normalization and aggregation behaviors remain valid |
| 50 | + |
| 51 | +### Full Suite |
| 52 | +- `npm test`: **FAIL** during pretest guard |
| 53 | + - `Shared extraction guard failed with 288 unexpected violation(s)` |
| 54 | + - Summary reported by guard: |
| 55 | + - `files_scanned=1322` |
| 56 | + - `total_violations=614` |
| 57 | + - `baseline_expected=397` |
| 58 | + - `baseline_unexpected=288` |
| 59 | + - `baseline_resolved=85` |
| 60 | + |
| 61 | +- `node ./scripts/run-node-tests.mjs`: **FAIL** |
| 62 | + - first failing gate: `tests/samples/SamplesProgramCombinedPass.test.mjs:40` |
| 63 | + - failure cause: hardcoded expected phase grouping (`phase-01` .. `phase-15`) no longer matches current repo phases (`phase-16` .. `phase-19` present) |
| 64 | + - all explicit tests prior to that gate passed in this run output |
| 65 | + |
| 66 | +## Lifecycle Leak Check |
| 67 | +- No lifecycle leak signal observed in targeted lifecycle tests. |
| 68 | +- Launch smoke completed full traversal with no failed entries. |
| 69 | + |
| 70 | +## Conclusion |
| 71 | +- Runtime lifecycle behavior is validated as stable for boot/run/shutdown/reset-reload/error paths. |
| 72 | +- Full-suite green status is currently blocked by two pre-existing global issues: |
| 73 | + 1. shared extraction guard baseline drift |
| 74 | + 2. sample program phase-range assertion drift |
| 75 | + |
| 76 | +No runtime/code changes were made in this PR slice. |
